Scirpus acicularis Linnaeus, Species Plantarum 1: 48. 1753.

"Habitat in Europa sub aquis purioribus." RCN: 409.

Lectotype (Egorova in Novosti Sist. Vyssh. Rast. 17: 69. 1980): Herb. Linn. No. 71.13 (UPS) . - Epitype (Kukkonen in Taxon 53: 180. 2004): Herb. Celsius 5: 677 (UPS) .

Current name: Eleocharis acicularis (L.) Roem. & Schult. ( Cyperaceae).

Note: The material designated as lectotype by Egorova is sterile, so a fertile sheet from the Celsius herbarium, also studied by Linnaeus, was designated as an epitype by Kukkonen.
